Abstract

A method of producing a photovoltaic element ( 1 ) comprises forming a photovoltaic member ( 11 ) on a first area (A 1 ) of a support member ( 12 ), such that the photovoltaic member leaves a second area (A 2 ) of the support member free, and bending the support member ( 12 ) in the second area (A 2 ) so as to enhanced the rigidity of the photovoltaic element ( 1 ). The support member ( 12 ) is substantially planar and is capable of being permanently deformed by bending, while bending the support member ( 12 ) may be carried out immediately after forming the photovoltaic member ( 11 ).

First claim

The invention claimed is:

1. A method of producing a photovoltaic element, the method comprising:
forming a photovoltaic member on a first area of a support member, such that the photovoltaic member leaves a second area of the support member free; and
bending the support member in the second area,
wherein the support member is substantially planar before the bending, and
wherein the support member is capable of being permanently deformed by the bending, and
wherein the bending the support member is carried out immediately after the forming the photovoltaic member.

2. The method according to claim 1 , wherein the support member comprises a metal sheet.

3. The method according to claim 1 , wherein the support member comprises a bendable plastic sheet.

4. The method according to claim 3 , wherein at least the first area of the support member is transparent.

5. The method according to claim 3 , wherein the bendable plastic sheet is made of a material taken from the group consisting of: polycarbonate, and polyacrylate.

6. The method according to claim 1 , wherein the support member has a thickness of between 0.5 mm and 4.0 mm.

7. The method according to claim 1 , wherein the bending the support member is performed by locally heating the support member in the second area.

8. The method according to claim 1 , wherein the forming a photovoltaic member comprises depositing semiconductor layers on the support member.

9. The method according to claim 8 , wherein the semiconducting layers are made of one or more materials taken from the group consisting of: cadmium telluride, copper indium diselenide, copper indium gallium diselenide, and amorphous silicon.

10. The method according to claim 1 , further comprising coating the support member prior to the forming the photovoltaic member.

11. The method according to claim 1 , further comprising cutting or drilling into the support member in the second area after the forming the photovoltaic member.

12. The method according to claim 11 , wherein during the cutting or drilling into the support member in the second area after the forming the photovoltaic member, the cutting or drilling is performed by one or more of the group consisting of: laser cutting and laser drilling.

13. The method according to claim 1 , wherein the forming the photovoltaic member and the bending the support member are carried out without movement of the photovoltaic member after the forming and before the bending operations.

14. The method according to claim 1 , wherein the support member comprises an aluminium sheet.

15. The method according to claim 1 , wherein the support member has a thickness of between 1.0 mm and 2.0 mm.

16. A photovoltaic element produced using a method comprising:
forming a photovoltaic member on a first area of a support member, such that the photovoltaic member leaves a second area of the support member free; and
bending the support member in the second area,
wherein the support member is substantially planar before the bending,
wherein the support member is capable of being permanently deformed by the bending, and
wherein the bending the support member is carried out immediately after the forming the photovoltaic member.

17. A building including the photovoltaic element according to claim 16 .

18. A photovoltaic building element comprising
a plurality of photovoltaic members formed in a first area of a support member, such that the photovoltaic members leave a second area of the support member free,
wherein the support member in the second area is permanently deformed by bending thus providing a modular building element with rigid side walls, and
wherein the building element is formed from a single 2D pre shape.

19. The photovoltaic building element according to claim 18 , wherein the photovoltaic members are connected by wiring circuitry integrally formed in the first area with the photovoltaic members, said wiring circuitry extending to and over the side walls.

20. The photovoltaic building element according to claim 18 , wherein the wiring circuitry is provided with interconnection components to electrically connect to another photovoltaic element or a power grid connection.
